Embodiment Construction

[0029]Referring now to the drawings, where like-referenced numerals refer to like or corresponding parts, the siphon-elbow of the present invention is shown and described below.

[0030]Referring first to FIGS. 1 and 2, the invention is shown, according to an exemplary embodiment thereof, in combination with a dryer 10 of the type used, for example, in the paper-making industry. The dryer 10 comprises a rotating cylinder 12 having a cylinder body 14 with an interior space 16. The cylinder body 14 has an inside surface 18 upon which steam condenses during operation of the dryer 10. The rotating cylinder 12 is coaxially journalled for rotatable support and includes at least one rotary joint at the end of journal 20. Journal 20 is hollow along its axial length, thus defining an internal hollow passageway 22. While this is a generally conventional construction for a steam-heated dryer 10, it will be appreciated by those skilled in the art that the forgoing configuration is exemplary only o...

Abstract

A siphon elbow for pivotally connecting separate horizontal and vertical siphon pipes in fluid communication, comprising a horizontal body and a pivot body. The horizontal body has a first, longitudinally-extending passageway defined therethrough between opposite first and second open ends, the first open end connectable to an end of a horizontal siphon pipe. A second passageway is defined transversely through the horizontal body and intersects the first passageway. The second passageway is at least partially defined by opposite openings in the horizontal body. The pivot body has a passageway defined transversely therethrough between first and second open ends, the second open end being connectable to an end of a vertical siphon pipe. The pivot body is freely rotatably supported within the second passageway of the horizontal body so as to permit the positioning of a vertical siphon pipe connected thereto between a first position, characterized in that the vertical siphon pipe is generally longitudinally aligned with the first, longitudinally extending passageway of the horizontal body, and a second position, characterized in that the vertical siphon pipe is aligned at an angle relative to the first, longitudinally extending passageway of the horizontal body.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]Not Applicable.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not Applicable.INCORPORATION BY REFERENCE OF MATERIAL SUBMITTED ON A COMPACT DISC[0003]Not Applicable.FIELD OF THE INVENTION[0004]The invention pertains generally to a siphon elbow of the type used to pivotally connect in fluid communication the separate horizontal and vertical siphon pipes of a siphon system in order to extract fluid from a rotating heat transfer drum such as is employed, for instance, in the paper-making industry. More particularly, the invention pertains to such a siphon elbow comprising a horizontal body connectable to an end of a horizontal siphon pipe, and a pivot body connectable to an end of a vertical siphon pipe. The pivot body is rotatably supported within the horizontal body so as to permit the positioning of a vertical siphon pipe connected thereto between a first position, characterized in that the vertical siphon pipe is gen...
